My main questions now are: is 1 month too short? is there a recommended school for a short program?
In terms of what I would like to achieve after 1 month – I would like to leave with the confidence that I could use the Japanese language to live there (order food, go to bank, search for apartment, go to doctor, etc) and travel (book flights, hotels, chat with strangers, etc). Not looking to achieve a fluency during this trip to understand the news or operate efficiently within the Japanese business environment.
